CU LTlVATO R.

SPECIFICATION forming part of Letters Patent No. 686,000, dated.November 5, 1901.

Application filed July 30, 1900. Serial No. 25,282. (No model.)

following is a full, clear, and exact descrip tion, reference being hadto the accompanying drawings, forming part of this specification.

My invention relates to straddle-row cultivators'; and it has for itsobject the provision of means whereby the driver from his seat on themachine can swing either or both of the cultivator-gangs to followirregularities in the row,and thus be enabled to cultivate close up tothe growing crop no matter how irregularly planted out of a straightline.

It also has for its object the provision of simplified means foraccomplishing the above results.

The novelty of my invention will be hereinafter set forth, andspecifically pointed out in the claims.

In the accompanying drawings, Figure 1, Sheet 1, is a side elevation ofa cultivator embodying my invention with the near wheel removed. Fig. 2,Sheet 1, is a plan view of the cultivator with part of the seat-beamsand;

the lifting-levers for the gangs removed. Fig.

mechanism. Fig. 4., Sheet 2, is a sectional 'end elevation on the dottedline 00 m of Fig. 3 looking to the left. Fig. 5, Sheet 2, is an enlargedsection detail side elevation of one of the link-retaining clips. Fig.6, Sheet 2, is a sectional end elevation on the dotted line y y lookingupward. Fig. 7, Sheet 2, is a front elevation of the spacing-bar and itsholders. Fig. 8, Sheet 2, is a side elevation of one of the holders forthe spacing-bar.

The same letters of reference are used to indicate identical parts inall the figures.

A A represent the supporting or carrying wheels journaled on stubs of astraddle-row axle B.

C is the pole or tongue, from which extend rearwardly theproperly-braced hounds D, whose rear ends are secured to the top of thearch of the axle B in the usual or any suitable manner. Frointhe forwardpart of the hounds depend two arms E, whose lower ends are braced byrearwardly and upwardly extendingrodsa b,whose upper ends are secured tothe hounds at the rear thereof, as seen in Fig. 1.

F is the doubletree, and G perforated links connecting its outer endswith the forward ends of the links H, extending to the lower cured tohanger-arms O, pendent from the hounds D, and to the arch of the axle.

P represents the usual hand-lock levers, pivoted to the hounds andengaging the segment-racks a. Links 6 connect the lower ends of thelevers P with the gang-bars J.

The cultivator thus far described is of a well-known type, and I willnow proceed to describe myimprovements which are to be added thereto orto any other form of straddle-row cultivator where adaptable.

Secured to the outer bar of each of the gangs is a vertical socketf,Figs. 3 and 4:, in which is pivoted a spindle g, dotted lines, Fig. 4.,carrying at its top an inwardly-extending horizontal plate h, upon whichare adj ustably bolted a rearwardly-extending arm t' and aninwardly-extending stirrup-piece j, with upward extensions 7a to form astirrup for the drivers foot. The arm 2' is backwardly and forwardlyadjustable on the plate It, and the stirrup-piecej is also laterallyadjustable on said plate and in addition can be adjusted angnlarlythereto by a slot 6 in said plate and a clamping-bolt on, passingthrough the stirrup-arm and slot Z. To the rear end of the arm vlof eachgang is pivoted a horizontal piece '22, whose outer end is forked, asseen at 0, Figs. 3 and 5., and lying within this fork is a link 19,whose inner end is horizontally pivoted to an aperture in the piece atand whose outer end, having an eye q thereon, engages upright.

by means of a vertical spindle r a clip 8, fast on the stub-spindles ofthe axle 13.

From the foregoing description it will be readily seen that the driverby placing his feet upon the stirrup-pieces j can swing the plate hforward or backward on its fulcrum g, thereby vibrating inward oroutward the gangs J to follow the sinuosities of the rows, for the eye qof the link p being fixed to the frame through the medium of the spindle'r and clip 8 the gangs J will be shifted laterally by the vibration ofthe stirrup-piece j. The leverage movement is entirely a horizontal one,and the arms of the levers, forming a bell-crank, are carried by andfulcrumed on the gang-bars. The pivoting of the links 1) to the pieces91 and their sliding connection at their outer ends with the spindles rpermit sufficient play to allow the lifting of the gangs from contactwith the ground by the action of the hand-levers P in transporting thecultivator from place to place and at the same time give sufficient playto permit the proper depth of penetration to the cultivator teeth orshovels when the machine is at work.

. As thus far described each gang has its own independent movementinwardly or outwardly; but to connect them together for simultaneousmovement I employ a spacingbar R, Figs. 1, 2, and 7, which is in theform of an arch with flattened lower and outwardlyextending portions t,whose under sides are provided with rack-teeth or serrations u to engageribs 13 in vertically-slotted pieces S, secured to the gang-bars, thevertical slots in said pieces serving to hold the spacing-barR Bylifting the bar R the gangs can be adjusted toward or from each otherand then be locked together by rengaging the ese,ooo

teeth of the bar It with the ribs 1; ofthe retaining-pieces S,as will bereadily understood. With the spacing-bar in place the driver can swingboth gangs simultaneously with either foot or with both feet, ifdesired.

The above-described mechanism for shifting the gangs is very simple inconstruction and efticient in action, and by the horizontal movement ofthe lever mechanism the gangs can be guided without practically alteringthe depth of penetration of the cultivator teeth or shovels, which is avery important feature.

Having thus fully described my invention, I claim-- 1. In a sulkystraddle-row cultivator, the combination with each gang,of the plate Itvertically pivoted to the gang,the stirrup-piecej, adjustable in and outupon and at angles to said plate, the rearwardly-extending arm iadjustable forward and back upon said plate, the piece n pivoted to therear end of said arm and having the fork 0, the link 1) pivoted to thepiece n and having at its outward end an eye q engaging a verticalspindle 7 carried by a clip 3 fast upon the main frame, substantially asdescribed.

2. In a sulky straddle-row cultivator, the combination with thecultivator-gangs, of a spacing-bar R in arch form and with lower lateralextensions having teeth on their under sides, and slot-ted pieces Ssecured to the gangs and having ribs '0 in said slots for uniting thespacing-bar to the gangs, substantially as described.

CLEMENT \V. MICHAEL.
